Sanchez has scored 73 goals in 147 appearances for Arsenal since his debut back in 2014 but the 28-year-old forward looked set for a sensational £60million switch to Manchester City on transfer deadline day.

However, the move never materialised and, with Sanchez out of contract at the Emirates next summer, the Chilean could leave for free ahead of the 2018/19 campaign.

The Sun suggest Mourinho is personally confident he can reach an agreement for the ex-Barcelona attacker and is determined to beat City to the signing.

Sanchez will be unable to sign a pre-contract with Mourinho’s Red Devils until the new year but it’s claimed an agreement can be made for the deal to eventually go through.

The Chile international is yet to score for Arsenal in the Premier League this season and started on the bench for the side’s 0-0 draw with Chelsea at the weekend.
